The Mind of the Meditator
Scientific American Just put out a decent summary of the current neuroscience research on meditation written by friends, Matthieu Ricard, Antoine Lutz, and Richie Davidson. I enjoyed reading the article and thought I’d share it here with some commentary. The article uses the same distinctions in meditation practice we outlined in our S-ART paper – That is Focused Attention, Open Monitoring (or Mindfulness), and Loving Kindness or Compassion (or ethical enhancement practices).
Essentially, they describe the act of meditating during Focused Attention similarly to the model below – A practitioner starts with the intention, orients attention and engages on object (Breath) – the mind becomes distracted and enters the mind-wandering default mode network – it realizes there is distraction (through decentering) and activates a salience network. Reorientation of awarenesss than involves dorsolateral prefrontal cortex and anterior inferior parietal lobe. I would further argue that the larger frontoparietal control network (including nodes of the salience network and lateral frontopolar cortex and even the lateral cerebellum) all contribute to the decentering, monitoring, and reorientation process. the ventrolateral prefrontal cortex concurrently helps with response inhibition.
Interestingly, the article also points out some of the morphological changes noted in a recent meta-analyses done by Kiran Fox HERE. The study found the frontopolar cortex and anterior insula were 2 brain regions with neuroplastic changes most often found in such studies of meditators.
New model of self-regulatory mechanisms for Yoga
How does yoga work? Is there a benefit to doing a bunch of postures, breathing, and meditation techniques while being crammed in a room full of Lululemon Athletica? A group of interdisciplinary researchers gathered at Kripalu Yoga center to discuss the potential mechanisms associated with yoga practice in contemporary settings, while also acknowledging the traditional, historical framework of ethically-motivated practices.
The manuscript (LINK) specifically poses a novel theoretical model of the potential self-regulatory mechanisms by which yoga facilitates adaptive reactions to physical and mental stress.
To give you a sense of what this model is depicting, I summarize below:
This systems network model includes the major limbs of yoga, represented as a skillset of four process tools: ethics, meditation, breath regulation, and sustained postures. As depicted in the model, cognitive, emotional, behavioral, and autonomic output in response to a stressor is modulated by a number of regulatory processes (yellow boxes) proposed to be influenced by the process tools (limbs of yoga, blue boxes). A stress response is often accompanied by cognitive, emotional, and behavioral output that includes emotional reactivity, negative appraisal, and rumination. In addition, autonomic output such as vasoconstriction, pain and/or tension, and inflammation often accompany maladaptive stress responses; (see solid black arrows). In chronic forms of such stress responses, negative, long-term consequences on health across bodily systems are often the result.
Our model proposes that yoga facilitates adaptive output (dotted lines), including long-term psychological and physical well-being, musculoskeletal strengthening, and prosocial behavior, through four primary factors in the context of stress: (1) an emphasis on interoception (body awareness) and bottom-up input (processing of information coming from the external and internal senses), (2) more efficient bidirectional feedback and integration with top-down (cognitive) processes, (3) increased phasic inhibition (red lines) of maladaptive forms of emotional, cognitive, and behavioral output (e.g., reactivity, negative appraisal, rumination) as well as autonomic output (e.g., vaso- and pulmonary constriction, inflammation, and muscle tension/pain), and (4) perceptual inference (using perceptual information from the body) rather than active inference (cognitive processing) for improved prediction (of the world) and Error Correction (less bias from previous mental habits). These four factors optimize self-regulation and improve the communication and flexibility by which top-down and bottom-up processes inform behavioral output in the context of physical and emotional stress. Through repeated yoga practice, there is a resulting skillful optimization of autonomic control in response to stressors on and off the yoga mat – keeping arousal at lower levels during stress-mediated challenge, maintaining positive appraisal and reinforcement, helping the practitioner stay relaxed with less effort, and facilitating rapid recovery of bodily systems under stress. A number of cognitive, emotional, behavioral, and autonomic mechanisms are proposed along with the underlying high- and low-level brain networks that support such mechanisms.
The takehome point: Yoga facilitates improved stress response modulation on and off the mat.
Self-Awareness, Self-Regulation, & Self-Transcendence (S-ART): A Framework for Understanding the Neurobiological Mechanisms of Mindfulness
Hi all,
I wanted to take this space-time to introduce you to an integrative systems-based neurobiological model and theoretical framework for understanding the mechanisms by which mindfulness functions to reduce attention-specific and affective biases related to self processing and creates a sustainable healthy mind. The model attempts to integrate findings from the extant empirical literature related to mindfulness with our growing understanding of the mechanisms for neurocognition and with traditional Buddhist systems from which contemporary practices of mindfulness originate. The paper in which this framework and model are discussed at length was recently published in Frontiers in Human Neuroscience. [Link]
Our method for understanding mindfulness has been to focus broadly on the goals of mindfulness as it is described in the early Buddhist suttas and in the Western medical model: To decrease mental suffering and create a sustainable healthy mind. In this context, we operationalize mindfulness in two ways: 1) As a broadly defined method for developing self-awareness, self-regulation and self-transcendence (S-ART); 2) As a continuous discriminative attentional capacity.
Our second formulation is one critical skill in a multidimentional skillset that is developed and strengthened through specific meditation practices. Other skills are described to function along with mindfulness to support S-ART.
To be clear, this is in no way a new definition that is meant to disparage Jon Kabat-Zinn‘s widely disseminated description: “Paying attention in a particular way, on purpose, in the present moment, non-judgmentally” – but more so an attempt to dismantle the concept into component parts so that we can better study it in the laboratory.
I discuss the framework in a recent talk given at the 23rd annual Trauma Conference in Boston, MA

The Wandering Mind vs. Mindfulness
Neuroimaging Research has grappled with the concept of a “resting brain”. Researchers interested in Consciousness have grappled with localizing subjective states of awareness and the elusive “self”. It seems that contemplative science is bringing both concepts to the table given the profound interest in tracing neurophenomenological states associated with “the self” and intentional, meditative practices.
All functional neuroimaging research has focused on Blood-oxygenation-level-dependent (BOLD) changes in the whole brain associated with a particular active, goal-directed, cognitive or emotional function and which has shown to be statistically different from BOLD activity across the whole brain during a “passive” baseline state. The baseline state that most researchers use is typically a 5-6 min long period of passive “rest”. The instructions are typically, “Let your mind freely wander” and “try not to think of anything in particular”. These instructions sound benign and appear to be the perfect baseline state, but as it turns out, [surprise…surprise] a wandering mind is quite active. The mind in this baseline state has shown to have a tendency to wander towards self-reflection (in the past and into the future). Some researchers have called this type of wandering, “mental time travel”.
Recently, a growing body of research has investigated the nature of this resting, or “default” state, and has found that brain activation previously considered to be spontaneous noise actually reflects the operation of active and functionally connected neural networks. These patterns of activation has been termed the default mode network (DMN), have been shown to increase during passive states of rest, to diminish during tasks involving attention or goal-directed behavior, and tend to implicate brain areas associated with self-reflection, internal mentation, and narrative self-focus. In many forms of psychopathology, the DMN has been found to be more active during resting states and less likely to decrease in activation during active goal-directed tasks, suggesting a relationship between psychopathology, excessive self-reflection or rumination [about past events], and increased self-projection [into the future].
In a recent study[Link] by friend and colleague, Judson Brewer at Yale University, adept meditators trained in meditation techniques rooted mostly in Theravada (vipassana/insight) traditions actively meditated using multiple types of meditation practices (Concentration, Loving-Kindness, Choiceless Awareness) while being imaged in the MRI. A “mind-wander” rest state was the baseline state in this case, and comparisons were made also between the adepts and a group of novices who had brief instructions how to perform each meditative practice.
As seen below, Experienced meditators demonstrate decreased DMN activation during meditation. Brain activation in meditators > controls is shown, collapsed across all meditations (relative to baseline). (A and B) BOLD activations were found to be greater in the left mPFC and PCC for adepts. Although, one should take note that the % change was very minimal (about .25 % at most). The mPFC and PCC are critical nodes of activation during typical mind wandering, self-reflection, and the core areas for the DMN.
Choiceless Awareness (green bars), Loving-Kindness (red), and Concentration (blue) meditations. Note that decreased activation in PCC in meditators is common across different meditation types. n = 12 per group.
What does this mean?
You may ask what this means and how it relates to mindfulness and mind-wandering. It suggests that adept meditators spend less time using the self-reflective network or “DMN” while meditating. This makes sense given the heavy reliance on concentration in these practices. But how about when adepts are simply “wandering” during passive rest? Are they like everyone else? Do they also reflect upon themselves in the past or into the future? This study did not quite capture the phenomenological differences between the groups, but it did find that the DMN had different functional connectivity patterns.
Using mPFC as a seed region for connectivity, they found increased connectivity with the fusiform gyrus, inferior temporal and parahippocampal gyri, and left posterior insula (among other regions) in meditators relative to controls during meditation. Using the PCC as a seed region, increased connectivity (compared with controls) was found with the dorsal ACC and DLPFC during all meditative states and baseline wandering, suggesting increased cognitive monitoring and working memory across both meditative and passive resting states. It would be helpful to know if there was a qualitative aspect of “wandering” that was about equal for meditators and controls.
Similarly, David Creswell and Lisa Kilpatrick demonstrated that 8-weeks of MBSR training showed increased functional connectivity of dmPFC (an anterior DMN region) with an auditory/salience neural network (especially with BA 22/39 (associated with auditory processing) and the dorsal ACC (involved in salience) . They suggest these results indicate greater positive coherence between self-referential, attention, and auditory sensory processing and may underlie greater attention and reflective awareness of auditory experience in MBSR trained subjects.
Again, the DMN is used here as a proxy for a “wandering mind”. Decreased activity in the cortical midline structures that make up this network reflects less self-reflection or narrative self-processing, and suggests more present-centered awareness, monitoring, and attention of interoceptive and exteroceptive stimuli in the environment and associated with the body. The reason I bring attention to this area of research is that contemplative neuroscientists will likely have to take these differences in the DMN between novices and adepts into consideration when scanning meditative states. In other words, a passive mind wandering state may be different between adepts and novices or naives. Thus, between groups comparisons should likely account for these differences and at the very least, quantify the qualitative aspects of mind wandering between groups.
ON THE OTHER HAND….
There is some evidence that mind wandering is adaptive. One study (for example) by Jonathan Schooler and colleagues demonstrates that increased mind wandering during a boring task increased creativity. Schooler has previously demonstrated a correlation between daydreaming and creativity—those who are more prone to mind-wandering tend to be better at generating new ideas.

Mechanisms of Mindfulness – Deconstructing the concept into psychological and neurobiological terms
A new paper has come out in the November issue of Perspectives in Psychological Science [Link]
This paper is one of the first to begin deconstructing the concept into component processes for investigation both at the clinical and basic science level. Previous attempts at operationalizing the concept have relied on the most widely cited definition:
paying attention in a particular way, in the present moment, and non-judgmentally. This definition comes from Jon Kabat-Zinn‘s book, “Coming to Our Senses” as:
moment-to-moment, non-judgmental awareness, cultivated by paying attention in a specific way, that is, in the present moment, and as non-reactively, as non-judgmentally, and openheartedly as possible. When it is cultivated intentionally, it is sometimes referred to as deliberate mindfulness. When it spontaneously arises, as it tends to do more and more the more it is cultivated intentionally, it is sometimes referred to as effortless mindfulness.
Other attempts at operationalizing the concept have relied on this definition for a framework. See table below
Here, we unpack the definition by illustrating very specific core neurocognitive processes that appear to be targeted in cultivating mindfulness as a state and trait. These processes are supported by the extant literature with specific neuroanatomical targets as well
I elaborate a bit more on dismantling mindfulness here [Link]
see vol 12 (2011) of Contemporary Buddhism for some great commentary on the difficulty of operationalizing mindfulness [Link]:
- Dreyfus, G. (2011). “Is mindfulness present-centred and non-judgmental? A discussion of the cognitive dimensions of mindfulness.” Contemporary Buddhism: An Interdisciplinary Journal 12(1): 41 – 54.
- Dunne, J. (2011). “Toward an understanding of non-dual mindfulness.” Contemporary Buddhism: An Interdisciplinary Journal 12(1): 71 – 88.

- Gethin, R. (2011). “On some definitions of mindfulness.” Contemporary Buddhism: An Interdisciplinary Journal 12(1): 263 – 279.
Many researchers now agree that mindfulness can be thought of as multi-dimensional set of skills that can be developed through the practice of specific types of meditation; however, we need to be careful not to confuse the concept of mindfulness with the common every-day usage of the term and contextualize the concept as a state, trait, type of practice, and intervention.

This was my 7th year attending the SRI and every year since 2005, scientists in this field grapple with operationalizing and deconstructing concepts that originate from an incredibly rich and complex historical context – The Buddhist “science of mind” . With an explosion of research and interest in the domain of mindfulness, science has yet to grasp the subtleties surrounding the heterogeneity of meditation practice and specifically those that seemingly cultivate mindfulness as a state, trait, and in terms of clinical interventions.
This year’s theme was devoted to the theme of ”New Frontiers in the Contemplative Sciences.” It was also paying tribute to Franciso Varela, the pioneer of neurophenomenology and the Mind and Life dialogues. A continued in-depth tri-logue has been the prescription that emerges for pushing this emerging field of contemplative science further…a trilogue between scientists, contemplative scholars/practitioners, and academics who have the ability to translate what one perspective or source of information can benefit in dissemination or integration with the other two. By continuing this trilogue, scientists will better be able to distinguish between what they should be studying, what they think they should be studying, and what they truly are studying….
This also translates to the practitioner him/herself who must distinguish between what he/she is doing while meditating in a specific style of practice, what they think they should be doing while practicing, and what they actually are doing. John Dunne, a Buddhist contemplative scholar/academic provided one of the more thought provoking presentations by challenging our conceptions of meditation and mindfulness as ‘Black box’ terms. He emphasized, “Historical contexts are not important if people are practicing something else”. Essentially, as scientists in this field, we MUST be absolutely clear what states of mind we are studying when we claim to be studying mindfulness.
More about Pain and Meditation
Can meditation practice eliminate pain? NO, but it can it reduce the emotional intensity in which it is anticipated and experienced!
There have been a few studies up to today (jan. 4, 2012) that have investigated the effects of specific meditative practices that involve the state of mindfulness on the experience of pain. Some studies suggest that pain centers (Anterior cingulate cortex, insular cortex, sensory cortex, pre-frontal cortex) that are normally active during acute pain are significantly reduced in activity while performing specific meditative practices. Other studies show the same reduction during resting brain activity of chronic pain sufferers in response to practicing these meditative states, specifically, and in contrast to allowing one’s mind to wander. These reports typically show increased pre-frontal cortex activity as a regulatory mechanism for suppressing the sensory and affective experience of pain. See this typical report from the BBC:
However, there are other reports that suggest meditators are not suppressing the sensory or affective experience of pain, but rather increasing their sensory and affective experience of pain, but without a prolonged, dull, or negative quality. In this case, research is beginning to reveal what may be more akin to equanimity and embodiment, two qualities that typically are cultivated along with mindfulness during specific meditative practices. Equanimity refers to the ability to experience the sensory event fully, with awareness, but to return back to some normative baseline rapidly once the sensory event is over. There is no ruminative quality, or perseveration of the emotion in response to the sensory event. Embodiment refers to the whole-body visceral experience of the sensory event. These studies have been showing increased activation in brain areas responsible for primary and associative sensory processing along with interoception (internal bodily experience).
———————
One example comes from a study by friend and colleague, Fadel Zeidan, who recently published in the Journal of Neuroscience, ” Brain Mechanisms Supporting the Modulation of Pain by Mindfulness Meditation” [Link]
Focused Attention meditation reduced BOLD activity related to afferent processing of pain stimulus (primary sensory cortex). Meditation was also associated with deactivations in areas related to ruminative types of thinking (Default areas). Decreased pain intensity ratings were also found to be associated with increased activity in ACC and right anterior insula, suggesting a site for pain modulation.

Short term “integrative body-mind training” (IBMT) improves self- and autonomic regulation
A group from Univ. of Oregon in collaboration with the Institute of Neuroinformatics and Laboratory for Body and Mind, Dalian University of Technology, Dalian, China has found more evidence (see 2007, 2009 and 2010 articles) that short-term meditation in the form of IBMT can improve self-regulation and components of attention.
What is IBMT? According to the authors, it was developed in the 1990s as a technique adopted from traditional Chinese medicine and incorporates aspects of meditation and mindfulness training. “IBMT achieves the desired state by first giving a brief instructional period on the method (we call it initial mind setting and its goal is to induce a cognitive or emotional set that will influence the training). The method stresses no effort to control thoughts, but instead a state of restful alertness that allows a high degree of awareness of body, breathing, and external instructions from a compact disc. It stresses a balanced state of relaxation while focusing attention. Thought control is achieved gradually through posture and relaxation, body–mind harmony, and balance with the help of the coach rather than by making the trainee attempt an internal struggle to control thoughts in accordance with instruction. Training is typically presented in a standardized way by compact disc and guided by a skillful IBMT coach”.
This group has been showing (2009) that Five days of integrative body–mind training (IBMT) (20 min/day) improves attention and self-regulation in comparison with the same amount of relaxation training. During and after training, the IBMT group showed significantly better physiological reactions in heart rate, respiratory amplitude and rate, and skin conductance response (SCR) than the relaxation control. Differences in heart rate variability (HRV) and EEG power suggested greater involvement of the autonomic nervous system (ANS) in the IBMT group during and after training. Imaging data demonstrated stronger subgenual and adjacent ventral anterior cingulate cortex (ACC) activity in the IBMT group. Frontal midline ACC theta was correlated with highfrequency HRV, suggesting control by the ACC over parasympathetic activity. These results indicate that after 5 days of training, the IBMT group shows better regulation of the ANS by a ventral midfrontal brain system than does the relaxation group.
The most recent 2010 article demonstrates that changes in white matter connectivity can result from small amounts of mental training. In this case, 11 h of IBMT increases fractional anisotropy (FA), an index indicating the integrity and efficiency of white matter in the corona radiata, an important white-matter tract connecting the anterior cingulate cortex (ACC) to other structures. 45 undergraduates to an IBMT or relaxation group for 11 h of training, 30 min per session over a 1-mo period. Before and after training we acquired brain images from each participant at rest for analysis of white matter by diffusion tensor imaging and gray matter by voxel-based morphometry.
The group goes a little far in speculating “IBMT could provide a means for improving self-regulation and perhaps reducing or preventing various mental disorders”, but the research is certainly promising for demonstrating plasticity in response to mental training
Measures of Mindfulness (revisiting the problems of defining the concept)
As clinicians, researchers, and basic scientists, we are slowly operationalizing the concept of mindfulness. It is important that we consider the cultural context from which the term arises and clearly distinguish it from secular practices like:
Progressive Muscle Relaxation (E.Jacobson)
Relaxation Response (H.Benson)
Biofeedback-induced relaxation
Situational Awareness (E. Langer)
These practices all involve:
Cultivation of Mental Discipline, primarily through discursive strategies.
Heightened ability to stop and start thoughts and emotions
Reduced susceptibility to mental habits; increased ability to develop new habits
